FIGURE 5.5
Three components of the non-uniform
deformation, called partial warps. (A) Partial warp at large
spatial scale, depicting an expansion of the mid-body rela-
tive to the head and caudal body; (B) partial warp at moder-
ate to small spatial scale, depicting a contraction of the
region between dorsal and adipose fins relative to the
length of the dorsal fin and caudal peduncle; (C) another
partial warp at moderate to small spatial scale, depicting a
shortening of the postorbital region relative to the preorbital
head and anterior post-cranial body.

geometric constructs
a function of the location and spacing of the landmarks of the ref-
erence form. They are obtained by a geometric decomposition of the landmarks of the ref-
erence form (as explained in detail in the next section). Although they provide a basis for
the tangent space, they cannot be interpreted except in these abstract terms
we cannot
say, for example, that one part of the change in the ontogeny of the fish is a shortening of
the region between dorsal and adipose fins relative to the dorsal fin and caudal peduncle.
